Having the top of the head lopped off, and the eyes so far toward the top, and then her shoulders fairly square, and that strongly patterned top she's wearing, all those things combined make this framing feel awkwardly bottom-heavy. Her wrist is very bright, and draws a lot of attention, so maybe tone that down a bit. This just isn't quite working as a square composition, as-shown. Maybe crop it in more tightly, so there's less visual weight at the bottom,and the head-chop makes more compositional sense.
There are times that cropping into the head makes sense, but again, in this example,. as-shwon originally, with so much of the bottom of the frame being clothes, and this bust-distance framing, it doesn't feel well-balanced. Maybe cropping this to a head and shoulder framing, instead of a bust, would work better in this square aspect ratio.
